Is LiH an acid or a base?

Lithium hydride that is LiH is basic in nature. It is a proton abstracting base. It reacts with acids like HCl.

Why is H2S a weak acid in an aqueous solution?

While H atom with S lacks H bonding and thus there bond can be broken very easily as compared to water. Thus due to this in H2O , H+ release is very difficult while H2S does it very easily and thus H2S becomes acidic.

Why is aqueous solution of FeCl3 acidic?

An aqueous solution of FeCl3 salt undergoes hydrolysis and forms HCl. This strong acid releases H+ ions in the solution. Hence, the resulting solution is acidic and turns blue litmus turns red.

Is AsH3 stronger than H2Se?

AsH3 is a stronger acid than HBr because As is larger than Br. H2SO4 is a stronger acid than H3PO4 because S is more electronegative than P. H2S is a stronger acid than H2Se because S is more electronegative than Se.

Why is LiH covalent?

Explanation: Lithium hydride does not exhibit many of the properties that we often associate with so-called “ionic” compounds. The 2s orbitals of Li and the 1s orbitals of H overlap within the octahedral network giving rise to bonds with significant covalent character.

What is LiH in chemistry?

In lithium: Chemical properties. Lithium hydride (LiH), a gray crystalline solid produced by the direct combination of its constituent elements at elevated temperatures, is a ready source of hydrogen, instantly liberating that gas upon treatment with water.

Is H2S more acidic than h2o?

Hydrogen sulphide (H2S) is certainly more acidic than the hydrosulphide ion (HS-). H2S is a weak acid and it ionises partially in water as per the following equation.

What happens when h2o reacts with H2S?

Because hydrogen sulfide combines easily with water, damage to stock tanks below water levels can be severe. Water with hydrogen sulfide alone does not cause disease. However, hydrogen sulfide forms a weak acid when dissolved in water. Therefore, it is a source of hydrogen ions and is corrosive.

Is NaC2H3O2 an acid or base?

NaC2H3O2 is an basic salt. In general, salts formed from the reaction between a weak acid and a strong base are basic.

Is an aqueous solution of FeCl3 acidic basic or neutral?

Aqueous solution of FeCl3 is acidic in nature.

When comparing H2Se and H2S H2Se is a stronger acid because the bond is?

In binary acids such as H2S and H2Se, the H–Se bonds is longer than the H–S bonds as Se is larger than S. The H–Se bond is therefore weaker than the H–S bond and H2Se is thus a stronger acid than H2S.

Is H2S more acidic than H2O?
